Although expert judgement is used in all forms of psychological measurement, clinical evaluation and the adoption of organised assessment programmes are the most common. Intelligence tests, personality tests, behavioural assessments, and clinical interviews all give potentially helpful information about the individual being evaluated. However, there needs to be an overall assessment of the examinee's level of functioning.
In other words, no one test offers a comprehensive picture of a person; it just delivers a specific piece of information about that person. One key role of assessment psychologists is to evaluate the information offered by several tests, interviews, and observations and to use this knowledge to create complicated and crucial judgements about persons.
Assessment in clinical settings refers to evaluating a patient's health status, symptoms, and medical history to determine a diagnosis and develop a treatment plan. This is usually done by a healthcare professional, such as a doctor or therapist, through various methods, such as psychological tests and personal interviewing. The goal of assessment is to gather as much information as possible to ensure that the patient receives the most appropriate and effective care.
Cognitive Assessment − The cognitive evaluation focuses on understanding the links between brain behaviour, information processing, and cognitive skills. Attention, perception, memory, schemas, learning (intelligence; accomplishment; aptitude), cognitive/development, creativity, language, problem-solving, decision-making, and judgement may be assessed. Specific forms of cognitive exams for examining these areas include neuropsychological tests, IQ tests, achievement and aptitude tests, and development tests.
General Mental Ability Assessment − The most widely used general mental ability tests are the Wechsler Intelligence Scales (WISC-I11 and WAIS-III) and the Stanford-Binet. These examinations have a dual purpose in developing individual evaluations. First, because many behavioural disorders are connected to intellectual impairments, an assessment of general mental aptitude is frequently necessary for understanding an individual's behaviour. Second, individual intelligence tests allow the examinee to see his or her behaviour in reaction to various intellectually challenging activities, providing information about the subject's perseverance, maturity, problem-solving approaches, and other traits.
Neurological Tests − The Bender-Gestalt and Luria-Nebraska Neuropsychological Test Batteries are commonly used to diagnose neurological diseases. The Bender-Gestalt is used to test perceptual problems and organic dysfunctions. In contrast, it may be used for a variety of diagnostic objectives. In contrast, the Luria Nebraska Battery assesses perceptual, motor, and intellectual functions that may be impaired by injury to particular brain areas.
Other Cognitive Assessments − There are various more reasons cognitive exams may be recommended. Cognitive evaluations may be necessary when people fail to meet predicted developmental milestones, such as language abilities. Self-recognition or recognition by others of non-normal (abnormal) behaviour, whether positive (superior intellectual talents, creativity) or wrong (attention issues, high emotional lability), frequently results in referrals for cognitive testing. Individuals, family, and friends usually notice significant changes in cognitive functioning, which often leads to visits to primary care physicians or emergency rooms; these health professionals may require the assistance of psychologists in diagnosing or understanding the cause of the behaviour change.
Various psychological tests are used in clinical settings. A well-known psychological test is the Rorschach, also known as the inkblot test. This test utilizes a series of inkblots to examine an individual's perception, thought processes, and emotional functioning. The test is often utilized to identify underlying emotional or personality disorders and gauge the success of interventions or treatments. Another commonly used test is the Thematic Apperception Test (TAT), which involves showing an individual a series of pictures or cards and asking them to create a story or narrative based on the image. The test is used to evaluate an individual's inner feelings, thoughts, and conflicts and identify underlying emotional or personality disorders. The Minnesota Multiphase Personality Inventory (MMPI) is a widely used test that assesses a wide range of personality traits and emotional states. The test consists of a series of true or false statements. It is often used to identify underlying emotional or personality disorders and evaluate the effectiveness of interventions or treatments. Two such tests are discussed
The Rorschach Inkblot Test − Rorschach Test was developed in the early 20th century by the Swiss psychologist Hermann Rorschach, who believed that the human mind has a universal tendency to project emotions, fantasies, and experiences onto ambiguous stimuli. The test consists of 10 standardized, black-and-white inkblots presented to the evaluated individual, who is asked to describe what they see in each blot. The Rorschach Test is based on the principle that people's perceptions and interpretations of the inkblots reveal their unconscious thoughts, feelings, and personality traits. The scores are then used to make inferences about the individual's personality and emotional functioning.
Sentence Completion Tests − Sentence completion tests are a psychological assessment tool that involves having an individual fill in the blank spaces in partially completed sentences. The individual is asked to complete each sentence in a way that reflects their thoughts, feelings, and beliefs. The responses given by the individual are recorded and then analyzed by a mental health professional to gain insight into their personality, emotions, and psychological functioning. Sentence completion tests are often used in psychotherapy to help the therapist understand the individual's thoughts, feelings, and experiences. They can also be a diagnostic tool to help identify mental health problems like depression, anxiety, or stress.
The Bender Visual-Motor Gestalt Test, also known as the Bender-Gestalt Test, is a psychological assessment tool used to evaluate visual-motor integration and perceptual-motor functioning in children and adults. The test involves having the individual being evaluated copy a series of abstract designs, called gestalts, onto a blank sheet of paper. The test is usually administered by a psychologist or other mental health professional and typically takes about 15-20 minutes to complete. The Bender Visual-Motor Gestalt Test results are analyzed based on several factors, including the accuracy and fluency of the copied designs, the presence of any distortions or deviations from the original design, and the overall gestalt quality of the copied designs. These factors can provide information about the individual's visual-motor integration, perception, fine motor skills, and ability to process and coordinate visual information.
Testing plays a vital role in clinical psychology. Tests such as the MMPI, PCL-R, and SAVRY are commonly used to provide valuable information about the individual being evaluated and assist in medical decision-making. However, the use of psychological tests in psychology is subject to specific ethical standards and guidelines, and it is essential to use them responsibly and ethically.
